    Platinum Mining Methods How Is Platinum Mined : Originally pgm was extracted using “the narrow reef method” in which miners use handheld pneumatic drills to create holes in the reef into which explosives can be loaded After the ore is released throughThere are several steps in the mining process of Platinum, the first one being extraction of the Platinum ore and bringing it above ground, there are two ways of doing this the first and older way is to blast the ore free with explosivesPlatinum Mining | Processing Equipment | Flow ChartVerder offers the following pump solutions in the PLATINUM MINING process Primary flotation VERDERFLEX VF PUMP: Pumping of thick slurries up to 80% solids Concrete thickener VERDERFLEX VF PUMP: Pumping of thick slurries up to 80% solids VERDERFLEX DURA PERSITALTIC PUMPS: ± 99% Accurate dosing VERDERMAG CENTRIFUGAL MAGDRIVE PUMP: Chemical transferPlatinum Mining Process Flow Diagram | Pumps

    Copper anodes from the converter process are dissolved electrolytically using an acid copper sulphate solution as an electrolyte The products of this operation are pure copper cathodes and an anode slime which may contain gold and small quantities of the platinum group metals The cells are constructed of rubberlined concrete Platinum Group Metals (PGMs) are recovered through underground and open pit mining from polymetallic sulphide ores containing PGMs, Nickel, Copper and other metals: Platinum (Pt), Palladium (Pd), Rhodium (Rh) and Ruthenium (Ru) are the most prevalent of the six PGMs, with Iridium (Ir), and Osmium (Os) found in much smaller quantitiesOVERVIEW OF PGM PROCESSING Anglo AmericanPLATINUM MINING AND EXTRACTION METHODS : The mining of platinum ores is alike gold mining The platinum orebody is a thin, tabular reef covering a vast area This enables a progressive method of mining which includes the drilling of the reef and blasting it to advance the faceplatinum mining, mining of platinum, platinum, platinum

  • Extraction and Refining of the Platinum Metals

    From this stage onwards the concentration of the platinum group metals is more rapid and the processes entirely chemical First the slime is subjected to roasting and leaching attacks to remove the last of the copper, nickel, iron and sulphur This produces an enriched slime running approximately 65 per cent of the platinum group metals and goldBecause platinum is so rare, it must be extracted after being mined through a process that involves crushing it into incredibly small particles and separating these particles from one another This is known as the flotation separation method, and produces a frothy layer of particles that can be skimmed to provide the extracted platinumHow Is Platinum Extracted? ReferenceFurthermore, these processes generate very toxic liquid streams and gas wastes that must be further treated, which do not meet the green environmental point of view of platinum recycling(PDF) Commercial Processes for the Extraction of Platinum

    However, in mining using 45 tonnes of ore to produce one gram of platinum would not be considered abnormal The extraction process Before a mine is even opened the potential site is explored and assessed for viability, in other words, is it profitable to extract the metal from the orePlatinum Metals Rev, 1963, 7, (41,136143 136 The earlier stages of the mining and recovery of the platinum metals from the Rustenburg Platinum Mines have been reviewed in some detail in this journal (I), while the geology of the Bushveld Igneous Complex and the platinum reefsconstitutingExtraction and Refining of the Platinum Metalsvery dangerous and 25% of the platinum mining incidents/accidents occur within 5 metres of the face Mining at a stope width of 18 metres, as with the LP equipment, compared with the targeted 11 metres results in a lower grade product This, in turn, results in less metal recovery, as shown inThe development and implementation of

    Platinum ore can be obtained through controlled explosions or by advanced mining techniques Once it has been mined, the platinum is extracted from the ore in the same way The platinum ore is not pure, so it is first crushed This produces many tiny particles that can be treated Air particles then bubble through an aeration tank and adhere toMining Platreef platinum ore at Mogalakwena, 320 km north of Johannesburg, is easy Daily blasts at the opencast mine break open the Platreef to extract the ore Then the hard work of processing this metresthick rock into millimetresthin metallicAn insight into platinum mining African ReviewPlatinum mining in South Africa In South Africa, the discovery of the first platinum nuggets dates back to 1924 The geologist Hans Merensky’s followup work resulted in the discovery of two deposits, each around 100km in length, which became known as the Bushveld Igneous ComplexPlatinum Minerals Council South Africa
